JAVA PROGRAM Chapter 7. PC #16. 2D Array Operations Write a program that creates a two-dimensional array initialized with test data. Use any primitive data type that you wish. The program should have the following methods: • getTotal. This method should accept a two-dimensional array as its argument and return the total of all the values in the array. • getAverage. This method should accept a two-dimensional array as its argument and return the average of all the values in the array. • getRowTotal. This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a row in the array. The method should return the total of the values in the specified row. • getColumnTotal. This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a column in the array. The method should return the...

Payroll Write a program that uses the following arrays: empId: an array of seven long integers to hold employee identification numbers. The array should be initialized with the following numbers: 5658845 4520125 7895122 8777541 8451277 1302850 7580489 hours: an array of seven integers to hold the number of hours worked by each employee payRate: an array of seven doubles to hold each employee's hourly pay rate wages: an array of seven doubles to hold each employee's gross wages The program should relate the data in each array through the subscripts. For example, the number in element 0 of the hours array should be the number of hours worked by the employee whose identification number is stored in element 0 of the empId array. That same employee's pay rate should be stored in element 0 of the payRate array. The program should display each employee number and ask the user to enter that employee's hours and pay rate. It should then calculate the gross wages for that employee (hours times...
